权利要求: C LA IM S1. A lubricating oil composition comprising:(a) from 45 to 75 mass% of a low viscosity first base oil component which is a Fischer-Tropsch derived base oil with a kinematic viscosity at 100°C in the range of from 3.5 to 7.0 mm2/s;(b) from 3 to 35 mass% of a high viscosity second base oil component which is a polyalkylene glycol;(c) an anti-foam additive which is a non-ionic surfactant, wherein mass% is based on the overall mass of the lubricating composition.2. A lubricating oil composition according to Claim 1, wherein the low viscosity first base oil component has a kinematic viscosity at 100°C in the range of from 4.0 to 6.0 mm2/s.3. A lubricating oil composition according to Claim 1 or Claim 2, wherein the high viscosity second base oil component has a kinematic viscosity at 100°C in the range of from 90 to 120 mm2/s, preferably 95 to 105 mm2/s.4. A lubricating oil composition according to any one of Claims 1 to 3, which also comprises a control component, which comprises one or more ester base oils.5. A lubricating oil composition according to Claim 4, wherein the ester base oils have an oxygen/carbon weight ratio of from 0.080 to 0.350, preferably from 0.080 to 0.300.6. A lubricating oil composition according to Claim 4 or Claim 5, wherein the ester base oils have a kinematic viscosity at 100°C of no more than 1 mm2/s, more preferably no more than 0.5 mm2/s, above or below that of the low viscosity first base oil component.7. A lubricating oil composition according to any one of Claims 4 to 6, wherein the control component, which comprises one or more ester base oils is present in an amount of from 2 to 10 mass%, based on the overall mass of the lubricating oil composition.8. A lubricating oil composition as claimed in any one of Claim 1 to 7, wherein the non-ionic surfactant is selected from poly-alkoxylated alcohols, poly-alkoxylated amines and mixtures thereof. 9. A method for lubricating an axle, said method comprising supplying to said axle a lubricating oil composition comprising:(a) from 45 to 75 mass% of a low viscosity first base oil component which is a Fischer-Tropsch derived base oil with a kinematic viscosity at 100°C in the range of from 3.5 to7.0 mm2/s;(b) from 3 to 35 mass% of a high viscosity second base oil component which is a polyalkylene glycol;(c) an anti-foam additive which is a non-ionic surfactant, wherein mass% is based on the overall mass of the lubricating composition.
